Showing 1 to 5.

1. Motors
The force of attraction or repulsion of magnetic fields causes electric motors to convert electrical energy to mechanical energy.

2. DC Motors
When a dc level is "wiped" onto the commutator (the separated contacts connected to the coils of wire) by a set of brushes (not shown), the current flowing through the coils of wire creates magnetic fields around the coils that are either opposed or attracted by the poles of the permanent magnet.

3. AC Motors
Motors run by alternating current operate on the same fundamental principle as those run by direct current—motion is produced because of the opposition of magnetic fields created by current flowing through wires.

4. Universal Motors
However, the motor has been designed so that when alternating current is applied to the motor, the magnetic fields from the armature and the field windings cause the armature to turn.
